ABOUT YOUR KLIPSCH PURCHASE
Your new Klipsch architectural speakers have been designed to deliver great sound while remaining unobtrusive wherever you install them. These models feature Controlled Dispersion Technology™. This allows you to point the sound as needed in a variety of installations. Any CDT is suitable for use as front, center or surround channels in audio or home theater applications, or as part of a distributed sound system. Any CDT model ending with SC is designed specifically for surround use in home theater applications.

2 Phillips Screwdriver
- Wire strippers
- Level
- Stud finder
- Saw
In-Ceiling Speaker Placement
Designed to function in any drywall or drop ceiling, Klipsch
in-ceiling speakers are engineered for years of performance. Minimum construction requirements call for drywall or other mounting surfaces to be at least 3/8″ thick. In drop ceiling installations, typical “drop in” 2’ x 4’ and 2’ x 2’ ceiling tiles are composed of low density materials which have the potential over time to sag and vibrate audibly. To maximize the acoustic performance of your in-ceiling speakers, Klipsch recommends you replace the original mounting panel with 1/2″ to 3/4″ plywood or medium density fiberboard (MDF) (see above).
Speaker Installation (for New Construction, skip to step #3)
- Cut the appropriate size opening in the wall or ceiling using the template provided. If the template is not available, cutout dimensions are provided on the Klipsch website,klipsch.com Sizes listed are minimum. If accuracy of cut cannot be achieved, you may add 1/4″ to each dimension. Be careful not to cut through any existing wiring or plumbing. Avoid compromising any fire stops between studs.
- Run speaker wiring (18 gauge minimum) to the openings. Be sure to comply with all building codes in your area.
- Attach the wire to the speaker using the wire’s color coding or markings as a guide to maintain proper polarity.
- Insert the speaker assembly into the opening and attach by tightening the four Phillips screws (below). The frame’s four “dogs” will swivel out and “sandwich” the wall and frame togeth-er as they are tightened. If you use a power tool to tighten these screws, please use a low torque setting. Failure to do so could result in damage to your speaker.
- Adjust the direction of the speaker by swiveling it to the left or right as needed. If desired, you may also adjust the tilt of the speaker and gently adjust the horn to the desired angle. Do not attempt to turn the tweeter stem while adjusting the swivel tweeter.
- At this point, you may paint the speaker grilles before attach-ing them to the speaker. Klipsch grilles are designed to accept most types of paint. Care should be taken to avoid excessive paint build-up in the grille perforations.
- Press the grille into place.
OPERATING CONTROLS
Mid-Bass and Tweeter Attenuator Switch (3000 and 5000 Series)
Some CDT models feature a Tweeter switch (3000 series) or both a Mid-Bass and a Tweeter switch (3000 & 5000 series) located on the front baffle. The switch allows a setting of either 0dB (normal) or –3dB in the respective frequency range. If installing in an acoustically bright room, such as a bathroom or kitchen, you may want to adjust the Tweeter level switch. If the speaker is located in a corner and produces too much bass, you may need to adjust the Mid-Bass level switch. The position of the switches should always be checked prior to attaching the grille.

FAQs
What kind of backing would you suggest installing under an attic? Will a piece of plain mdf board placed on top suffice?****
I built mine as it was being built, and MDF does work well. With cheap oak
plywood, I constructed a box that went from rafter to rafter, and it has been
very successful.
Don’t just bury it under insulation, as I’ve advised others to do, as I don’t
think that will serve as a strong enough speaker boxes. In such case, your
attic essentially serves as the box.
Linked up via wifi?****
No! A receiver/amplifier must be connected to the CDT-3650-C II ceiling speaker, which is passive and unpowered.
Is this a pair, and can I use it to replace the old ceiling speakers and have it support Dolby Atmos in addition to being back speakers?****
The CDT-3650-C II is offered for sale singly, not in pairs. Dolby Atmos, which is “surround sound from above you,” may be reproduced quite well with in- ceiling speakers.
I need advice on which ceiling speakers to use for my back speakers and Dolby Atmos audio. For my main, I already have RB 61ii.****
Speak with Klipsch since they are the experts on which speakers from their ranges should be coupled for the greatest sound.
Do I need to construct a backbox for these speakers? I have ceilings with open tiles.****
The back of the speaker does not require an enclosure with the CDT-3650-C II. Having an enclosure might occasionally cause the sound quality to decline.
With a tiny 20w amp, could I obtain reasonable sound from this speaker?****
Depending on what you plan to use them for Although they aren’t used as much as front or surround speakers because I’m using them for dolby atmos, they still produce excellent sound.
Does the grille or plate come with this sparkler? Can the angle of this speaker be changed?****
The in-ceiling installation speaker CDT-3650-C II does have a magnetically attracted grill.
Anyone else having trouble with this speaker’s scant to nonexistent bass?****
I installed the speakers in a ceiling that had an attic access above, so I used the ceiling joists as the two sides and added the other two sides.
Bluetooth or WiFi connectivity?****
No! A receiver must be attached to the CDT-3650-C II’s passive, non-powered ceiling speaker via speaker wire.
Is it okay if these are mounted on the wall? The circular wall speakers are better than the rectangular ones, in my opinion.****
I think a skilled sound engineer could make them function in a wall. They cannot be mounted on a wall. For the price, mine are fantastic, however I mounted them in the ceiling.
